KVMD 1.88: Tailscale support

We added Tailscale to the OS repository for easy access to KVM from an external network via VPN. Updated documentation is here.

For very old computers a new mixed Arduino HID mode has been added: PS/2 keyboard + USB mouse. This is a great alternative to the PS/2 keyboard only mode that was added earlier.

All new project supporters are added to the thank you list in the About dialog in Pi-KVM and to the github. Thanks again!

To update:

rw
pacman -Syu
reboot
